CALIBRATION OF A WEIGHING LYSIMETER FOR MEASURING COCOA EVAPOTRANSPIRATION [PDF]
Revista Caatinga, 2020 ABSTRACT Well-operated and calibrated weighing lysimeters reliably determine the water demand of agricultural crops, and the quality of the data is evaluated through the error analyses attributed to the instrument. The objective of this study was to determine performance parameters of a weighing lysimeter and to evaluate its adequacy for the direct ...

Development of an IoT based weighing type micro-lysimeter for soilless cultivation
The Indian Journal of Agricultural Sciences, 2020 In the present study, an attempt has been made to apply Internet of Things (IoT) for precise irrigation management. A weighing type micro-lysimeter based on IoT was developed to measure the amount of water consumed by the cucumber crop grown in soilless

Viscous Flow Approach to Rapid Infiltration and Drainage in a Weighing Lysimeter
Vadose Zone Journal, 2018 Rapid infiltration and drainage in a free-draining weighing lysimeter are assessed with a viscous flow approach that is based on the concept of moving water films. The two parameters and of the film per unit volume of the permeable medium together with

Evaluation of growth-stage-specific crop coefficients of maize using weighing lysimeter
Soil and Water Research, 2015 Weighing lysimeters are used to measure crop evapotranspiration (ETC) during the growing season. A ratio of crop evapotranspiration to reference evapotranspiration (ETo) determines a crop coefficient (Kc) value, which is related to a specific crop growth

Construction and assessment of a hydraulic weighing lysimeter
African Journal of Agricultural Research, 2016 Hydraulic weighing lysimeters have been showing good results in evapotranspiration studies. Thus, the aim of this study was to construct, calibrate, and assess a small (0.7 m3) and low cost hydraulic weighing lysimeter. The lysimeter consists of two containers.

Water Distribution in an Arid Zone Soil: Numerical Analysis of Data from a Large Weighing Lysimeter
Vadose Zone Journal, 2018 Although desert soils cover approximately one third of the Earth’s land surface, surprisingly little is known about their physical properties and how those properties affect the ecology and hydrology of arid environments.

Large Variations in the Transpiration of Sorghum Canopies Under High Evaporative Demand Are Positively Related to Water Use Efficiency. [PDF]
Plant Cell EnvironABSTRACT Transpiration restriction under high vapour pressure deficit (VPD), measured indoors with individual plants, increases water use efficiency (WUE). However, VPD is not the only factor driving transpiration, individual plants in a field rapidly become a canopy, and reports on the transpiration restriction versus WUE are scant.
